Amphenol ICC 68000-204 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68000-204 is a rectangular connector header designed for through-hole mounting applications. This 4-position, single-row connector operates at 0.100" (2.54mm) pitch and supports 3A per contact with an operating temperature range of -65°C to 125°C. The part is currently active in production status. Substitute parts may be required due to inventory constraints, design revisions, or application-specific requirements that demand alternative electrical or mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68000-204 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — mechanical and electrical compatibility requirement
• Contact Type: Male Pin — determines mating interface
• Mounting Type: Through Hole — PCB assembly method
• Current Rating: 3A per Contact — electrical load capacity
• Operating Temperature Range: Must support -65°C ~ 125°C minimum
• Material Flammability Rating: UL94 V-0 — safety compliance

The substitute part 4-103185-0 (TE Connectivity AMP Connectors) shares the same pitch, contact type, mounting method, current rating, and flammability rating. However, this part is listed as Obsolete and features a 40-position configuration compared to the 4-position main part. The operating temperature range differs (-65°C ~ 105°C versus -65°C ~ 125°C), and the insulation height is reduced (0.090" versus 0.100").

Parameter Comparison

Engineering Selection Recommendations

The 68000-204 is the preferred choice for new designs due to its Active product status and extended operating temperature range (-65°C ~ 125°C). The part meets UL94 V-0 flammability requirements and maintains consistent electrical specifications across its 4-position configuration.

The substitute part 4-103185-0 shares critical electrical parameters (pitch, contact type, current rating, and flammability rating) but carries an Obsolete product status. This part features a 40-position configuration, which is mechanically incompatible with applications designed for 4-position headers. Additionally, the reduced operating temperature maximum (105°C versus 125°C) and lower insulation height (0.090" versus 0.100") present design constraints for temperature-sensitive or space-critical applications.

Substitution of 4-103185-0 for 68000-204 is not recommended for direct replacement due to position count mismatch and obsolete status. If position-specific alternatives are required, consult the substitute chain referenced in the 4-103185-0 documentation (0022284363, 9-146280-0).

Frequently Asked Questions (FAQ)

Q: Can the 4-103185-0 directly replace the 68000-204 in existing designs?

A: No. The 4-103185-0 is a 40-position connector, while the 68000-204 is a 4-position connector. Position count is a fundamental mechanical and electrical parameter that determines PCB footprint and mating interface compatibility. Direct substitution is not possible.

Q: What is the significance of the Obsolete product status for 4-103185-0?

A: Obsolete status indicates that the part is no longer in active production. While existing inventory may be available, long-term supply cannot be guaranteed. For new designs or production runs, the Active status of 68000-204 ensures continued availability and support.

Q: Are the operating temperature ranges compatible?

A: The 68000-204 operates from -65°C to 125°C, while the 4-103185-0 operates from -65°C to 105°C. Applications requiring operation above 105°C must use the 68000-204. The 20°C difference in maximum temperature may be critical for high-temperature environments.

Q: Do both parts meet the same flammability standards?

A: Yes. Both the 68000-204 and 4-103185-0 meet UL94 V-0 material flammability ratings, ensuring compliance with safety requirements for applications where flame resistance is specified.

Q: What are the differences in contact material and finish?

A: The 68000-204 uses Phosphor Bronze contacts with Gold or Gold, GXT™ finish. The 4-103185-0 uses Copper Alloy contacts with Gold finish on the mating surface and Tin-Lead finish on the post. Both maintain the same mating contact finish thickness (15.0µin / 0.38µm), but the post finish differs, affecting soldering characteristics and long-term reliability.

Q: Is the insulation height difference significant?

A: Yes. The 68000-204 has an insulation height of 0.100" (2.54mm), while the 4-103185-0 is 0.090" (2.29mm). This 0.010" difference may impact PCB layout, clearance requirements, and mechanical fit in space-constrained applications.

Q: What is the current rating for each part?

A: Both parts support 3A per contact, meeting identical electrical load requirements for standard applications.

Q: Are there RoHS compliance differences?

A: The 68000-204 is RoHS non-compliant, while the 4-103185-0 status is listed as Not applicable. RoHS compliance requirements should be verified against specific application and regional regulations.
